Abstract
Purpose :
This study is to investigate visual outcome after implantation of PanOptix in META-PM grade 0 , grade 1 and grade 2 with low risk of macular pathological progression high myopic eyes.
Methods :
A total of 32 eyes with high myopia (axial greater than 26mm or spherical equivalence is less than -6.00D) diagnosed as cataract were implanted with a trifocal intraocular lens (PanOptix) in our hospital. PM macular staging is divided into three groups: META-PM 0 grade group (13 eyes), META-PM 1 grade group (10 eyes) and META-PM 2 grade group (9 eyes). The visual acuity, fundus and META-PM staging before operation, 1 day after operation, 1 week after operation and 1 month after operation were analyzed.
Results :
The mean age was 55.48±11.63y. The preoperative average axial length was 26.37±1.38mm, the average spherical equivalent was -7.94±3.57, the average preoperative corrected distance visual acuity (Logmar) was 0.38±0.38. There was no statistically difference of postoperative uncorrected distance visual acuity (Logmar) (0.04±0.12 in grade 0 group, 0.09±0.16 in grade 1 group and 0.12±0.19 in grade 2 group ), uncorrected intermediate visual acuity (0.07±0.14 in grade 0 group, 0.17±0.14 in grade 1 group and 0.14±0.17 in grade 2 group), and uncorrected near visual acuity (0.06±0.09 in grade 0 group, 0.19±0.16 in grade 1 group and 0.18±0.16 in grade 2 group) between the three groups(P>0.05) after 1-month follow-up. One week after the operation, 2 patients developed intraocular hypertension of 21mmHg-30mmHg, and they all returned to normal after discontinuation of corticosteroids, and no other complications occurred.
Conclusions :
Uncorrected distance vision of high myopia with META-PM grade less than grade 3 after trifocal intraocular lens implantation were all significantly improved compared with preoperative corrected distance vision. META-PM grade was not correlated with postoperative visual acuity after trifocal intraocular lens implantation with META-PM grade less than 3 after 1-month follow-up. Long term follow-up result needs further study.
